Abstract
Description
Die Erfindung betrifft die Verwendung von Blech aus einer Aluminiumlegierung mit einem Legierungsanteil von Aluminium größer als 97% für das Abschirmen von Wärme in Kraftfahrzeugen.The invention relates to the use of aluminum alloy sheet with a Alloy content of aluminum greater than 97% for the Shielding heat in motor vehicles.
Aufgrund der für eine Wärmeabschirmung besonders vorteilhaften physikalischen Eigenschaften von Aluminium - hoher Reflektionsgrad im Infrarot-Bereich und sehr gute Wärmeleitfähigkeit - haben sich Aluminiumlegierungen als Werkstoff zur Herstellung von Wärmeabschirmblechen als Standardlösung durchgesetzt. Um die genannten physikalischen Eigenschaften des Aluminium umfangreich zu nutzen und den hohen Anforderungen an die Umformbarkeit des Werkstoffes bei der Herstellung von Wärmeabschirmblechen gerecht zu werden, werden zur Zeit etwa 80% der Wärmeabschirmbleche in Al 99,5 (AA1050) gefertigt. Eine hinreichend gute Umformbarkeit dieses Werkstoffs durch Tiefziehen ist gewährleistet, da die Dehnung (A5) von Al 99,5 bei etwa 45% liegt.Due to the especially for a heat shield advantageous physical properties of aluminum - High reflectance in the infrared range and very good Thermal conductivity - have aluminum alloys as Material for the production of heat shields as Standard solution enforced. To the mentioned physical properties of the aluminum extensively too use and the high demands on the formability of the material in the production of To meet heat shields, are currently about 80% of the heat shields in Al 99.5 (AA1050) manufactured. A sufficiently good formability of this Material by deep drawing is guaranteed, as the Elongation (A5) of Al 99.5 is about 45%.
Nach DIN weist Al 99,5 neben Aluminium folgende
Legierungsanteile in den angegebenen Grenzen auf:
Die Verwendung von Al 99,5 ist zwar unter den Gesichtspunkten hohe Wärmeabschirmung und hohe Umformbarkeit vorteilhaft, gleichzeitig jedoch unter verschiedenen anderen Aspekten problematisch. Zum einen weist Al 99,5 eine geringe Festigkeit auf. Beim Einsatz von Wärmeabschirmblechen im Kraftfahrzeugbau werden jedoch erhebliche Anforderungen an die Festigkeit gestellt, die sich beispielsweise aus den Einwirkungen des Fahrtwindes oder von Spritzwasser bei hohen Geschwindigkeiten sowie der Einwirkung von Steinschlag ergeben. Die geringe Festigkeit von Al 99,5 führt dazu, daß zur Gewährleistung der erforderlichen Festigkeit Blechformteile mit größerer Dicke eingesetzt werden müssen, was einerseits die Kosten erhöht und andererseits das Gewicht des Wärmeabschirmbleches vergrößert. Die geringe thermische Stabilität von Al 99,5 - Kriechen setzt bereits bei Temperaturen von über 150 °C ein - führt zu einer im Einsatz geringen Formstabilität, die jedoch zur Einhaltung der Abstände des Wärmeabschirmbleches gegenüber beispielsweise einem Katalysator und einem Fahrzeugunterboden zur Gewährleistung der erwünschten Wärmeabschirmung notwendig ist. Al 99,5 weist aufgrund der hohen Dehnungswerte, wie bereits erwähnt eine gute Tiefziehbarkeit auf. Die Dehngrenze ist mit etwa 30 N/mm2 jedoch gering. Die geringe Dehngrenze von Al 99,5 begrenzt die Möglichkeiten während des Umformprozesses bei der Herstellung von Wärmeabschirmblechen.Although the use of Al 99.5 is advantageous from the viewpoints of high heat shielding and high formability, it is problematic at the same time from various other aspects. On the one hand Al 99.5 has a low strength. However, when heat shields are used in motor vehicle construction, considerable demands are placed on the strength, which results, for example, from the effects of the wind or splashing at high speeds and the effect of falling rocks. The low strength of Al 99.5 results in that to ensure the required strength sheet metal parts must be used with greater thickness, which on the one hand increases the cost and on the other hand increases the weight of the Wärmeabschirmbleches. The low thermal stability of Al 99.5 creep sets in at temperatures above 150 ° C - leads to a low dimensional stability in use, but to maintain the distances of the heat shield against, for example, a catalyst and a vehicle underbody to ensure the desired heat shield necessary is. Al 99.5, due to the high elongation values, as already mentioned a good thermoformability. However, the yield strength is low at about 30 N / mm 2 . The low yield strength of Al 99.5 limits the possibilities during the forming process in the production of heat shields.
Ein weiteres Problem insbesondere im Dauereinsatz von Wärmeabschirmblechen besteht darin, daß Al 99,5 eine hohe Neigung zur Grobkornbildung insbesondere nach geringen Kaltumformungen aufweist. Diese Grobkornbildung, insbesondere bei der zwangsläufigen thermischen Belastung von Wärmeabschirmblechen, führt dazu, daß speziell in Radien die Gefahr einer Rißentstehung beispielsweise in Befestigungspunkten des Wärmeabschirmbleches besteht. Another problem especially in continuous use of Wärmeabschirmblechen is that Al 99.5 a high Tendency to coarse grain formation, especially after low Has cold transformations. This coarse grain, especially with the inevitable thermal load of heat shields, causes that specifically in Radii the risk of cracking, for example, in Attachment points of the Wärmeabschirmbleches exists.
Auch sind die dynamischen Lastaufnahmen von aus Al 99,5 gefertigten Wärmeabschirmblechen aufgrund der starken Grobkornbildung unzureichend. Die aus strukturellen Gründen an sich erwünschte Verwendung von Noppenblechen ist in Verbindung mit dem Einsatz von Al 99,5 problematisch, da eine Formstabilität nicht gewährleistet werden kann. Diese Formstabilität wird dadurch beeinträchtigt, daß bei Noppenblechen an den umgeformten Noppenbereichen mit einer verstärkten Grobkornbildung nach einer Wärmebelastung gerechnet werden muß.Also, the dynamic load pickups are made of Al 99.5 manufactured heat shields due to the strong Coarse grain formation inadequate. The structural Reasons for desirable use of Noppenblechen is in connection with the use of Al 99.5 problematic because a dimensional stability is not guaranteed can be. This dimensional stability is characterized impaired that in Noppenblechen to the formed Pimple areas with increased coarse grain formation must be expected after a heat load.
Ausgehend von dem zuvor beschriebenen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Aluminiumlegierung für das Abschirmen von Wärme in Kraftfahrzeugen zur Verfügung zu stellen, die gegenüber Al 99,5 eine weiter verbesserte Umformbarkeit, eine verbesserte Festigkeit, eine höhere thermische Stabilität und eine geringere Neigung zur Grobkornbildung aufweist.Based on the previously described prior art The invention is based on the object, a To provide aluminum alloy for the shielding of heat in motor vehicles, the compared to Al 99.5 a further improved formability, an improved strength, a higher thermal Stability and less tendency to coarse grain formation having.
Erfindungsgemäß ist die zuvor hergeleitete und aufgezeigte Aufgabe dadurch gelöst, daß Blech aus einer Aluminiumlegierung mit einem Legierungsanteil von Aluminium größer als 97% für das Abschirmen von Wärme in Kraftfahrzeugen verwendet wird, wobei Eisen und gegebenenfalls Mangan die einzigen Hauptlegierungskomponenten bilden und deren Legierungsanteil die Summe der Legierungsanteile der Restlegierungskomponenten um mindestens den Faktor 5 übersteigt. Durch die erfindungsgemäße Übergewichtung von Eisen und gegebenenfalls Mangan, somit von höchstens zwei für Al 99,5 nach DIN zulässigen Hauptlegierungskomponenten gegenüber den nach DIN für Al 99,5 zulässigen Restlegierungskomponenten ist gewährleistet, daß die erfindungsgemäß verwendete Aluminiumlegierung ein deutlich homogeneres Gefüge aufweist, wodurch die Festigkeit und die Streckziehbarkeit verbessert ist und gleichzeitig die Neigung zur Grobkornbildung reduziert ist. Gleichzeitig bleibt die Dehnbarkeit zumindest auf gleichem Niveau. Gemäß einer ersten Ausgestaltung der erfindungsgemäßen verwendeten Aluminium-Legierung wird eine Verdoppelung der Streckgrenze bei gleichzeitiger Erhöhung der Festigkeit um bis zu 50% dadurch gewährleistet, daß die Summe der Legierungsanteile der Hautplegierungskomponenten die Summe der Legierungsanteile der Restlegierungskomponenten um mindestens den Faktor 10 übersteigt.According to the invention, the previously derived and indicated task solved in that Aluminum alloy sheet with an aluminum alloy content greater than 97% is used for shielding heat in motor vehicles, with iron and possibly manganese being the only ones Main alloy components and their alloying content is the sum of Alloy shares of the remaining alloy components um exceeds at least the factor 5. By the Overweight of iron and optionally manganese according to the invention, thus of at most two for Al 99.5 according to DIN permissible main alloy components compared to those permitted by DIN for Al 99.5 Residual alloy components ensures that the Aluminum alloy used in the invention clearly more homogeneous structure, whereby the strength and the stretchability is improved and at the same time the The tendency to coarse grain formation is reduced. simultaneously the elasticity remains at least at the same level. According to a first embodiment of the invention used aluminum alloy will double the Yield strength while increasing strength up to 50% by ensuring that the sum of the Alloy shares of skin plucking components Sum of the alloy shares of the remaining alloy components by at least a factor of 10.

Eine Optimierung der Streckgrenze und der Festigkeit ist bei einer erfindungsgemäß verwendeten Aluminiumlegierung dadurch gewährleistet, daß der Legierungsanteil von Mangan zwischen 0,35% und 0,45% liegt.An optimization of yield strength and strength is in an aluminum alloy used according to the invention thereby ensures that the alloy content of manganese between 0.35% and 0.45%.

Die Eigenschaften einer erfindungsgemäß verwendeten Aluminiumlegierung werden sowohl für den Fall, daß Eisen und Mangan die Hauptlegierungskomponenten bilden als auch für den Fall, daß Eisen die einzige Hauptlegierungskomponente bildet, dadurch gewährleistet, daß der Legierungsanteil von Eisen zwischen 1,25% und 1,35% liegt.The properties of a used according to the invention Aluminum alloy are used both in the event that iron and manganese form the main alloying components as well in the event that iron is the only one Main alloy component forms, thereby ensuring that the alloy content of iron is between 1.25% and 1.35%.

Dadurch, daß der Legierungsanteil von Silizium 0,2% nicht übersteigt, ist gewährleistet, daß die erwünschte Erhöhung der Streckgrenze und der Festigkeit bei zumindest gleichbleibender Dehnbarkeit und reduzierter Grobkornbildung erreicht wird. Aus denselben Gründen ist es vorteilhaft, wenn der Legierungsanteil von Magnesium 0,003% und/oder der Legierungsanteil von Zink 0,03 nicht übersteigt.Because the alloying content of silicon is not 0.2% ensures that the desired Increasing the yield strength and strength at at least constant extensibility and reduced Coarse grain formation is achieved. For the same reasons it is advantageous if the alloy content of magnesium 0.003% and / or the alloy content of zinc 0.03 not exceeds.
Die nach DIN für Al 99,5 ebenfalls zulässigen Legierungsanteile Chrom und Titan beeinträchtigen die erwünschten Eigenschaften der erfindungsgemäß verwendeten Aluminiumlegierung auch oberhalb der nach DIN vorgegebenen Legierungsanteile zunächst nicht. Zur Gewährleistung der erwünschten Eigenschaften der erfindungsgemäß verwendeten Aluminiumlegierung ist es jedoch vorteilhaft, wenn der Legierungsanteil von Titan 0,03% und/oder der Legierungsanteil von Chrom 0,02% nicht übersteigt.The also permitted according to DIN for Al 99.5 Alloy shares chrome and titanium affect the desired properties of the invention used Aluminum alloy also above the DIN initially not given alloy shares. to Ensuring the desired properties of However, it is the aluminum alloy used in the present invention advantageous if the alloy content of titanium is 0.03% and / or the alloying level of chromium 0.02% not exceeds.
